Very old AMIBCP needed

Hi, I'm looking for AMIBCP that's older than version 7.00.beta11 (This one is released in 1999). I'm currently working on BIOS for motherboard that was manufactured in 1995/1996 (very old eh, just like manufactured in the prehistoric era by today standard 8O ). Too bad I gotta working on this oldies...

I have an unused hosting until february next year at http://www.bios-hacking.com/. I'm very busy to fill it with something at the moment. I don't even have time to migrate my old website. You can use it, if you like. Just PM me :wink:

hmm.. this eModules. It's interesting, I wonder where I can download one of the BIOS binary image (AMIBIOS8 with eModules). The press release says that it's an expansion module. It's possible that it's implemented just like an expansion ROM, but takes a quite different approach in the way to execute...

XGROUP is decompressed and then relocated to segment 1000h by the system BIOS ("original.tmp") in Award v6.00PG. Note that this task is the very first POST routine/POST jump-table entry in Award v6.00PG. Thus, if you find a code in POST that do a far call to this segment (1000h). It calls the relate...

IIRC, the Video Mode initialization is carried out just before displaying the EPA Logo (or whatever logo in may contain) in Award BIOS. However, my experience is limited to Award v4.50. You might want to look for "80 8EE1 0110 F646 1430" byte pattern. 80 8E E1 01 10 or byte ptr [bp+1E1h], 10h F6 46 ...

after looking up the old Geode LX BIOS binary that I've been working on (it's based on Award BIOS v4.5), it seems that the "microcode" is buried deep in the system BIOS binary (original.tmp) since there is no separate microcode files in the Geode LX binary. Thus, it's very possible that the modifica...

Hi Maman, also AMD processors have microcodes! yes, you're right. I was thinking about the different microcode update mechanism when I was replying :wink: . I've been working with Geode LX BIOS a year ago. It was modified Award 4.50PGNM BIOS. But, I don't remember if one of it's BIOS module is a mi...

IIRC AMD Processor do not use any microcodes at all (all flavors of Athlon, maybe K6x too). The functionality of microcodes is replaced by writing "something" directly to the MSR(Machine Specific Register). I don't really sure if Geode is using microcodes. Geode was made by the previous CPU design t...
